Indeed, but oil comes first. The infrastructure isn't there for renewables yet. We also can't store it and distribute it. It comes into the grid in bursts. It's also expensive.

The end goal should be renewables (and nuclear, I'd argue). But in the mean time we need energy independence as a stepping stone. If we can do it here, and then have it for cheap at that, we can slowly integrate more renewables into the system. There isn't a switch we can just throw and go "No more oil. Tomorrow we start with wind".

Like, the natural gas boom right isn't the greenest thing. It's not the ideal solution. But it's a heck of a lot cleaner than coal. And it's local. So, use it as an interim solution.
